I have in my possession one complete suspension kit for E36 (see other thread for E30 kit), which includes a matched set of shocks, struts, and springs. Even among many choices for E36 suspension, this kit is quite a good upgrade to a sportier, stiffer ride at a reasonable price. Bilstein doesn't really provide the information of how much it will lower your car, but I have it on good authority that it will drop the car 1.5". I would like $1050+Tax for this kit, which will include Bilstein's Limited Lifetime warranty - something you don't get if you buy used shocks and springs.

I sold one of these kits for E36 not too long ago and I will provide this link to the thread so you can get a better idea from other max members of how the kit feels on the car.
